Abstract
The invention is a reduced radar detectable runway. In detail, the invention comprises a runway having a plurality of holes randomly orientated and randomly dispersed across and along the surface thereof. The holes are preferably polygons, and ideally square in shape, and filled with a dielectric material. Additionally, the minimum necessary perimeter of the runway should include an extended portion in an irregular pattern about a least a portion of the necessary perimeter. This portion should also incorporate the randomly positioned and orientated holes.
